Nakuba Kokubili Ukuhlolwa Kwe-Astain Voltage kanye Nokuhlolwa Kwamanje Kokuvuza Kungasetshenziswa Ukuhlola Amandla E-Insulation Yethagethi Ehloliwe, Kunomehluko Obalulekile Enqubweni Yokuhlola Nemiphumela.Ukuhlolwa kwe-Windstand Voltage Kwenziwa Ngaphansi Kwe-Voltage Ephezulu Ngemuva kokuthi Isistimu Yokufaka I-insulation yazo zonke Izingxenye Zamanje Eziphethe Ithagethi Ehloliwe Izungeza Isikhashana.Ukuhlolwa Kwamanje Kokuvuza (Ukuthinta Kwamanje) Kwenziwa Ngaphansi Kwezimo Zogesi Kusetshenziswa Izisetshenziswa Zokuhlola Ukulingisa Ukuphazamiseka Komzimba Womuntu.
Nakuba Lezi Zivivinyo Ezimbili Zihlukile, Ziwusizo Kakhulu Ekuqinisekiseni Ukuphepha Komkhiqizo.Ukuhlolwa Kwe-Windstand Voltage Kuyisivivinyo Semijikelezo engu-100% (RoutineTest), Futhi Ukuhlolwa Kwamanje Okuvuzayo Kubhekwa Njengohlobo Lokuhlola.
Ngokwamukelwa Okubanzi Kwemihlahlandlela Yanamuhla Ye-Voltage Ephansi (LVD), Ukumelana Nokuhlolwa Kwe-Voltage Futhi Ukuvuza Izivivinyo Zamanje Kuzoba Izivivinyo Zomugqa Wokukhiqiza Okujwayelekile, Nokuhlolwa Okwengeziwe, Okufana Nokuhlolwa Kwe-Insulation Resistance kanye Nokuhlolwa Kwe-Ground Resistance, Kuzongezwa.
Imikhiqizo Kagesi Esezingeni Eliphezulu Kufanele Iphumelele Ukuhlolwa Kwezinga Lokuphepha Ezicini Eziningi, Okuhlanganisa Ukuhlolwa Kokumelana Nomthamo Wegesi, Ukuhlolwa Kokumelana Nokufakwa Kwamandla Amanzi, Ukuhlolwa Kwe-Ground Impedance, Ukuhlola Okuvuza Kwamanje (Ukuthinta Kwamanje), Njll. Kulezi Zinto Zokuhlola Ezijwayelekile Zokuphepha, Ingxenye Eyinkinga Ukuvuza Ukuhlolwa Kwamanje (Thinta Ukuhlola Kwamanje).Lo mkhiqizo Ungakala Ukuvuza Okungajwayelekile Kwamanje Ngokuvuza Kwamanje Ukuhlola.Ukuvuza Kwamanje Umhloli Kuyithuluzi Lokuhlola Elivamile Lokuhlola Ukuvuza Kwamanje.
Ukuhlolwa Kokuvuza Kwamanje (Touch Current).
Eminyakeni yakamuva, Imithethonqubo eminingi Yokuphepha Komkhiqizo Idinga Imikhiqizo Ukuthi Ihlolelwe Ukuvuza Kwamanje, Kungakhathaliseki ukuthi Isekuhlolweni Kwedizayini Yomkhiqizo Noma Ukuhlolwa Komugqa Wokukhiqiza, Ikakhulukazi Esigabeni Sokuklama.Ngemva kwalezi Zivivinyo, Onjiniyela Bokuklama Umkhiqizo Bangathola Ulwazi Oluningi Olubalulekile Mayelana Nobuqotho Bomkhiqizo, Ukwenza Umkhiqizo Uhambisane Nemithetho Yokuphepha.Lapho Ithagethi Ehloliwe Ivivinywa Ngaphansi Kwe-Voltage Eyengeziwe Noma Izikhathi Ezingu-1.1 Zokukhipha Igesi Eyengeziwe Evamile, okungukuthi, Lapho Umkhiqizo Uhlolwa Ngaphansi Kokusetshenziswa Kwangempela Nezimo Ezinephutha, Ekuhlolweni Kwamanje Kokuvuza Kwe-Ground, Intambo Ephansi Yethagethi Ehloliwe Kukalwe Ukuqinisekisa Ukugeleza Buyisela Okwamanje Kulayini Omaphakathi Wohlelo.Ovivinyweni Lwamanje Lokuvuza KweKhabhinethi, Okwamanje Kusukela Emaphuzwini Ahlukene Kwikhabhinethi Kuya Ephuzwini Elingathathi hlangothi Lohlelo Kuyakalwa.
Ukulinga I-Voltage (I-Insulation) Ukulingisa Uhlelo Lokufaka I-insulation Lethagethi Ehloliwe Kumele Ikwazi Ukumelana Nogesi Ophakeme Kakhudlwana Isikhathi Esithile Ngaphansi Kwezimo Ezikude Ngokudlula Ukusetshenziswa Okuvamile.Ukuhlola I-Voltage Yomkhiqizo Kusho Ukuthi Ingasebenza Ngokuphepha Ekusetshenzisweni Okuvamile Futhi Ingakwazi Ukumelana Nokushintsha Okujwayelekile Okudlulayo.Lokhu Ukuhlola Okuwusizo Kumhlaba Wonke, Futhi Abakhiqizi Bomkhiqizo Bangaphinda Bayisebenzise Ukuze Baqinisekise Ikhwalithi Eyisisekelo Yomsebenzisi Yophawu Lomkhiqizo.
Ngenhlanganisela Elula Yokuhlola, Ukuxhumana Phakathi Kwesihloli Se-Voltage Kanye Nethagethi Ehloliwe Kungadlula Ebhokisini Lesokhethi Noma Umthofu Wokuhlola, Bese I-Instandard Voltage Tester Isebenzisa I-Voltage Kokuhlosiwe Okuhloliwe.Uma Ukuvuza Okudlulayo Kwamanje Kukukhulu Kakhulu, Isihloli Se-Windstand Voltage Sizobonisa Amaphutha, Okubonisa Ukuthi Impokophelo Ehloliwe Ayiphumelelanga Ukuhlolwa.Uma Kungekho Ukuvuza Okudlulele Kwamanje Okuhloliwe, Isihloli Se-Voltage Esimelayo Sizobonisa Ukuthi Manje Sesidlulile, Sibonisa Ukuthi Okuhlosiwe Okuhlosiwe Manje Sekuphumelele Ukuhlolwa.Inani Lokuvuza Okudlulele Kwamanje Linqunywa Inani Elimisiwe Leleveli Yamanje Ephezulu Evumelekile, Engalungiswa Ku-standard Voltage Tester Ukuqinisekisa Ukuthi Ukuhlolwa Kudlulile.I-Windstand Voltage Tester Empeleni igxile Esilinganisweni Sokufakwa Kwamandla Phakathi Kwamakhondatha Aphethe Manje Namakhondukta Angathwali Amanje, Njengezinsimbi Ezidaluliwe Ezingathwali Zamanje.Lena Indlela Enhle Yokuthola Izinkinga Zokuklama Umkhiqizo, Njengokubeka Amakhonduki Eduze Kakhulu.
Izimo Zokusebenza Zokuhlolwa Kwe-Voltage Ye-Programmable Leakage Current Tester
Ukuvuza Kwamanje Okulawulwa Ngohlelo Sikhuluma Ngokujwayelekile, Imininingwane Yezokuphepha Nezinhlangano Ezilawulayo Azinalo Inani Elilinganiselwe Lokuhlolwa Kwengcindezi Evamile, Kodwa Kunqunywa Umkhiqizi Womkhiqizo Ohloliwe.Uma Inani Lamanje Lokuvuza Kwe-Voltage Lingakacaciswanga, *Indlela Yokuhlola Enhle Iwukusetha Inani Lamanje Lokuvuza Kwe-Voltage Elifinyelela Izinga Lohambo, Eliphakeme Kancane Kunevelu Lokuhlolwa Okuhlosiwe Lapho Ukunikezwa Amandla Kuvamise Ukunqanyulwa. Valiwe Ngaphansi Kokuhlolwa.
Ukumelana Nokuvuza Kwe-Voltage Yamanje * Izicaciso Ezivamile Zokuphepha Nezicaciso Kungabhekisela Ezincazelweni Eziningana ze-UL, Ngokuvamile “120k Ohm” Njengereferensi.Lokhu Kucaciswa Kusetha Ukumelana Okugxilile, Okuzoholela Nakanjani Ekukhombeni Kwephutha Ekuhlolweni Kwe-Ainstand Voltage.Ekuqaleni, i-1000 Volts Plus Ephindwe Kabili I-Voltage Eyengeziwe Yezisetshenziswa Esohlangothini Lwe-Quilt.Lesi Isilungiselelo Esivamile Sokumelana Nokuhlolwa Kwe-Voltage.Njengoba I-Voltage Eyengeziwe Yezinjongo Zokuhlola Eziningi Ezisetshenziswa E-United States Ingama-120
Esivivinyweni Samanje Sokuvuza, Okwamanje Okukaliwe Kungasetshenziswa Ukubala Isilinganiso senani Lokusetha Uhambo Lwamanje Lokuvivinya Ukumelana Nevoltage.Lokhu Kuyivelu Elinganiselwe Kuphela, Ngenxa Yokuchezuka Kwezingxenye Zezisetshenziswa Kungase Kubangele Umehluko Omncane Ekuvuzeni Kwamanje Ukufundwa Kwezinjongo Zokuhlola Ezihlukile.Lapho Kubalwa Izilungiselelo Zamanje Zokuvuza Okufanelekile, Kubaluleke Kakhulu Ukuqonda Umehluko Oyisisekelo Phakathi Kokuhlolwa Kwe-Astain Voltage kanye Nokuhlolwa Kwamanje Kokuvuza.Nakuba Iningi Labahloli Bamanje Abavuza Behlinzeka Ngezivivinyo Zokushintsha Kolayini Wokukhiphayo (L/N), Bakala Kuphela Ukuvuza Kwamanje Kusuka Engxenyeni Ephethe Yamanje Kuya Odabeni Lwedivayisi Ehlolwayo Ndawonye.Ukuhlolwa Kwe-Antstand Voltage Kukala Ukuvuza Kwamanje Kwezingxenye Ezimbili Eziphethe Zamanje Ndawonye, Ngaleyondlela Kubonisa Ukuvuza Okuphakeme Ukufundwa Kwamanje.Umthetho Owusizo Wesithupha Ukumisa Uhambo Lokuhlola I-Voltage Yamanje Lufinyelele Cishe Ku-20% Kuya Ku-25% Womphumela Wesibalo Wefomula elandelayo:
(Ukumelana Nokuhlola I-Voltage Voltage/Ukuvuza Kwamanje Ukuhlola Voltage) *Ukuvuza Ukuhlolwa Kwamanje Kwamanje = Inani Elilinganiselwe Lokumelana Nokuhlola I-Voltage Yamanje.
